Product Description
The Allen-Bradley 1794-VHSC is a Flex I/O Very High Speed Counter Module, catalog number 1794-VHSC, Series A. It provides two independent input channels capable of counting pulse inputs at frequencies up to 1 MHz, with support for 5V DC or 15 to 24V DC terminations. The module supports multiple operating modes including counter, encoder X1, X2, and X4, and period/rate measurement. Two isolated output groups are included, rated at 0.5A at 5V DC and 1.0A at 12 to 24V DC. The module mounts on DIN rail in an open-style IP20 enclosure and connects to the Flex I/O bus via a terminal base such as the 1794-TB3G or 1794-TB3GS. This listing is for a used, field-removed unit. Buyers matching this exact catalog number for replacement, maintenance sourcing, or spare inventory should confirm series and terminal base compatibility with their existing system configuration. The successor replacement identified by Rockwell Automation is the 5094-HSC.
